The alleged victim of a high-speed road rage incident in South Australia will be recalled to give more evidence in court.

Zephatali Walsh said he feared for his life last July when another driver fired five shots at his car during a pursuit on the Eyre Highway near Kimba at close to 200 kilometres per hour.

Alleged gunman Michael Craig Anderson, 53, pleaded guilty to aggravated endangering life, but his plea was rejected by prosecutors and he is on trial in the Supreme Court for attempted murder.

During cross-examination, the Perth man told the jury he feared Mr Walsh's intentions after a minor collision.

He said Mr Walsh tried to force his car off the road and he did not know what would happen next.

Anderson said he had no intention of killing Mr Walsh and fired at the road hoping to encourage Mr Walsh to leave him and his wife alone.

"Also to let him know it wasn't a toy and it wasn't wasn't a starting pistol and I wasn't shooting blanks," he told the court.

The accused man said he was "incredibly accurate" with a handgun and able to shoot and hit golf balls from 50 metres away.

Anderson said Mr Walsh lied to emergency services about the speed he was driving at and the number of and timing of shots fired.

"For whatever his reasons, he's made a blue. He's picked on this elderly couple with Western Australian plates for whatever reason, now I don't know whether it was highway robbery or not, it did occur to me, and he's got the fright of his life because this silly old bugger had got a handgun ... a big scary gun," Anderson said.

After giving evidence Anderson withdrew his guilty plea to endangering life, meaning the jury will have to consider both charges once it deliberates.
